Symptom Profiles and Intensive Treatment Outcomes in Sexual Minority and Heterosexual Patients With OCD

Sexual minority (SM) individuals appear to be at greater risk for obsessive-compulsive disorder (OCD). Despite this, little is known about OCD presentation and treatment outcomes among SM individuals. Although some research has suggested that SM individuals may be more likely to endorse intrusive thoughts related to violence/sex/religion compared to heterosexual individuals, extant literature has neglected to examine potential differences across different SM groups, a notable limitation given the apparent differences in the types of minority stress that each group experiences and the unique health disparities affecting each group. The current study sought to address these gaps by examining potential differences in OCD symptom severity, presentation, and treatment outcomes using analysis of variance and profile analysis in a clinical sample of 1,502 cisgender patients diagnosed with OCD enrolled in intensive OCD treatment (87.5% heterosexual, 6.6% bisexual, 4.7% lesbian or gay, and 1.1% questioning). Replicating previous research, neither OCD severity nor treatment outcomes differed by sexual orientation, and findings extended previous research that no differences across SM groups were observed, either. However, contrary to previous research, there was also no evidence for unique profiles of OCD symptoms across sexual orientation groups, and questioning individuals reported significantly less severe symmetry symptoms compared to heterosexual and bisexual individuals. Findings are encouraging in that they suggest that cisgender bisexual, lesbian or gay, and questioning individuals with OCD can still benefit significantly and to the same degree as their cisgender heterosexual peers in intensive OCD treatment. Potential explanations for conflicting findings regarding symptom profiles are discussed.
